特殊说明
383b: DESULFONAUTICUS MEDIUM
1. Solution A is sparged with 80% H2 and 20% CO2 gas mixture to reach a pH below 6 (at
least 30 min), then dispensed under the same gas atmosphere into anoxic Hungate-type
tubes or serum vials to 30% of their volume and autoclaved. Solution B is autoclaved
separately under 80% N2 and 20% CO2 gas atmosphere. Solutions C and E are autoclaved
under 100% N2 gas. Solution D is prepared under 100% N2 gas and filter-sterilized. To
complete the medium appropriate amounts of solutions B to E are added to the sterile
solution A in the sequence as indicated. Final pH of the medium should be 7.0 – 7.2.
2. After inoculation pressurize vials to 2 bar overpressure with sterile 80% H2 and 20% CO2
gas mixture.
3. Note: Addition of 10 - 20 mg sodium dithionite per liter (e.g. from 5% (w/v) solution
freshly prepared under N2 and filter-sterilized) may stimulate growth of some strains at the
beginning. For transfers use 5 - 10% inoculum. Incubate all strains in the dark.
For DSM 4206, DSM 15269: Supplement medium with 1.00 g/l Na-acetate, 2.00 g/l
Trypticase peptone and 2.00 g/l yeast extract added to the autoclaved medium from
sterile anoxic stock solutions prepared under N2 gas.
For DSM 15286, DSM 21156, DSM 101864: Supplement medium with 1.00 g/l Na-acetate
and 1.00 ml/l seven vitamins solution (see medium 503) added to the autoclaved medium
from sterile and anoxic stock solutions. Vitamins are sterilized by filtration. Adjust pH of
medium to 6.5 - 6.7 prior to inoculation.
For DSM 111414: Adjust pH of final medium to 6.6.
